Dell 4100/200 manual Remove the computer cover, Remove the Ultra/Wide Scsi cable from the computer

2.Remove the computer cover.

See “Removing the Computer Covers” in Chapter 7.

CAUTION: See “Protecting Against Electro- static Discharge” in the safety instructions at the front of this guide.

3.Remove the Ultra/Wide SCSI cable from the computer.

•One end of the cable attaches to the SCSI host adapter connector labeled “SCSI BACK- PLANE” on the system board.

•The cable’s other end attaches to the connector labeled “SCSI” on the SCSI backplane board.

4.Install the PowerEdge Expandable RAID Con- troller host adapter card in one of the peripheral component interconnect (PCI) expansion slots.

See “Installing an Expansion Card” in Chapter 8.

5.Connect the new Ultra/Wide SCSI cable provided in the PowerEdge Expandable RAID Controller kit to the connector labeled “SCSI” on the SCSI backplane board (see Figure 10-3).

6.Connect the other end of the SCSI cable to the PowerEdge Expandable RAID Controller host adapter card.

To identify the correct connector, refer to documen- tation for the PowerEdge Expandable RAID Controller host adapter card.

NOTES: If you will be attaching external SCSI devices using the external SCSI connection slots on the com- puter’s back panel, follow steps 7 through 10.

If SCSI devices are connected using the external SCSI connection slots, Ultra SCSI mode is not supported.

7.Connect the SCSI external access cable from the host adapter kit to the Ultra/Wide SCSI host adapter connector (labeled “SCSI BACK- PLANE”) on the system board.

See the documentation that came with each device for information on cabling that device as part of a daisy chain.

8.Attach the other end of the SCSI external access cable to the computer’s back panel. If you are attaching multiple external SCSI devices, daisy- chain the devices to each other using the cables shipped with each device (see Figure 10-4).
